BOLSTER FOR CARS.

SPECIFICATION forming part of Letters Patent No. 701,837, dated J' une10, 1902.

VApplimation led August 19, 1901. Serial No. 72,531. (No model.)

To aZZ whom, vt wwf/y concern.: n

Be it known that I, SAMUEL PEESCOTT BUSH, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin' and State ofOhio,-have invented a certain new and useful Improvement in Bolstcrs forCars, of which the following, taken in connection with the accompanyingdrawings, is a specification.

The first of the objects of ymy present invention is the provision of acar-bolster having an integrally-formed compression member and strutlcombined with a separatelyformed tension member and means for securingthe ends ofthe tension and compression members together.

Another objectofmy invention is the provision of a bolster` .having anintegrallyformed compression member and strut combined with aseparately-formed tension member, the compressionmember being formedwith the side bearings also integral therewith.

Another object of my invention is the construction of a car-bolsterhaving an integrallyformed compression member and strut, with which arealso formed integrallyy the side bearings and center plate.

Another object of my invention is the combination,with the compressionmember, strut, and tension member of a bolster, of a. separately-formedtension-member seat for transmitting the strain between the strut andtension member.

The above, as well as suc-h other objects as may hereinafter appear, Iattain by means of a construction which Ihave illustrated in preferredform' in the accompanying drawings, in which- Figure l isa plan view ofa bolster embodying my invention. section thereof, taken on the line 2of Fig. 1. Figi 3 is an inverted plan view of my improvement applied toa bolster. Fig. 4 isa section on the line -l of Figs. 1 and 2. Fig. 5 isa section on the line 'of Figs. 1 and 2.

In carrying out mypresent invention I provide rst an integrallyvformedpreferably cast compression member and strut, which I have marked 6, ofwhich the compressionmember portion 7 is preferably of channel shape andthe strut portion 8 arranged to project downwardly from said channel andFig. 2 is a longitudinal which, as shown, is braced by means of thefianges 7a of the compression member. The tension member 9 is preferablyof a strap form and where it engages the strut is provided with atension-member seat 10, as shown in Fig. 5, which can be made separatefrom the strut for convenience of the casting of the combinedcompression member and strut, but which by the use of a little coringcould be cast integral with the compression member and strut, ifdesired, and would be thus formed also within the contemplation of myinvention generally considered.

The compression-member part 7 is preferably made with a center plate 11and also vside bearings 12 and brackets 13, all formed integral with thecompression member, as shown in Fig. 2, and the ends of the bolster areprovided with end castings 14, between which and the compression memberthe ends of the tension member 9 are secured by means of rivets'l,passing through both the com-l pression and tension members and the endcasting.

Having thus described my invention, what I claim as new, and 'desire tosecure by Letters Patent, is-

1. A car-bolster comprising an integrallyformed compression member andstrut, in combination with a single plate tension member, and means forsecuring the ends of the tension and compression members together,substantially as described.

2. A car-bolster comprising an integrallycast compressionV member andstrut, in combination with a separate single plate tension member, andmeans for securing the said tension member and compression membertogether at the ends of the same, comprising end castings secured uponone side of the tension member, and rivets passing through the endcastings, the tension member, andthe compression member, substantiallyas described.

3.y A car-bolster having a channel-iron compression member, saidcompression member having a center plate and side bearings formedintegrally therewith, a tension member, a strut, and means for securingthe compression member and tension member together at the ends of thesame, substantially as described.

4. A car-bolster comprising an integrally- IOC member, and means forsecuring the con1 pression member and tension member together at theends,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

SAMUEL P. BUSH.
